I Need a script for changing scenes please give me a working anser
Yeah, exactly like what @NikSpace said. You can use `Application.LoadLevel()` in two ways.
First of all, make sure the scenes you want to load have been added in the build setting in the File menu. Then when you look in the build settings you will see that each scene in there has a number next to it.
To link to that level, you can go, `Application.LoadLevel(1);` that would load the level that has one next to it and so on etc...
You can also go: `Application.LoadLevel("thenameofyourscene");` that will also work!
Here is the scripting reference for Application(): http://unity3d.com/support/documentation/ScriptReference/Application.html
Hope this helps you!
